Neither Grimes nor Hartline has returned punts in the NFL, but both did it in college. Hartline, in fact, was quick to point out after practice that he holds the Ohio State school record — he had a 90-yard punt return for a touchdown against Kent State as a sophomore in 2007.

Marcus Thigpen handled both punt and kickoff return duties for the Dolphins in 2012, although Davone Bess also was used on punt returns. With Bess having been traded to Cleveland during the draft, the Dolphins could be looking for somebody else to complement Thigpen.
